摘要
在团氿湖区布置7个采样点,用GARMINMap60CSX手持式GPS导航仪定位,进行叶绿素a(Chl-a)、总磷(TP)、总氮(TN)、透明度(SD)、高锰酸盐指数(CODMn)、溶解氧(DO)等理化指标监测,并应用模糊层次分析法综合分析团氿水质(春、夏、秋、冬时湖水的Chl-a、TP、TN、SD、CODMn)。结果表明:湖区模糊层次分析综合指数为0.61,水质达中度污染状况,水质有进一步恶化的风险,需加强管理与改善。模糊层次分析法对团氿水污染分析结果与单因子法评价水质基本相符,值得推广应用。
Seven sample sites were selected inTuanjiu lake, these sites were located with handheld GPS navigators in group GARMINMap6OCSX. Six physiochemical indexes including total nitrogen （ TN ） , total phosphorus （ TP ） , chlorophylla （ Chl-a ） , potassium permanganate index （ CODM. ） , transparency （ SD ） , dissolved oxgen （ DO ） were monitored. Fuzzy analytic hierarchy process （ FAHP ） was utilized to comprehensive evaluate the water quality （ including TN, TP, Chl-a, CODMn, S]） ） of Tuanjiu Lake. The result shows that the value of fuzzy hierarchy of comprehensive analysis index is 0.61. Water quality reach pollution levels, it needs to strengthen management and improvement to aviod further deterioration. Water quality evaluation result of Tuanjiu Lake by FAHP is consistent with the single factor evaluation for water quality, which is feasible and worth popularization.
